Home Materials Stainless steel for turning and milling

Stainless steel turning milling

Stainless steel is high-alloy steel with a chromium content of more than 10.5%, giving it very good corrosion resistance and good mechanical properties. Stainless steel is used for turning and milling parts for a wide range of industries, from medical technology to the chemical and pharmaceutical industries to mechanical and plant engineering.

Our stainless steel alloys

We offer you a choice of various stainless steel alloys that differ significantly in terms of their mechanical properties and machinability. Our overview will help you to select the ideal material for your turning parts and milling parts.

Alloy	Material costs	Manufacturing costs	Tensile strength N/mm²	Hardness HB	Description
1.4021 X20Cr13	€€€	€€€	700 – 850 Hardened: 1520	225 Hardened: 445HB(47HRC)	Hardenable, martensitic steel characterized by its high polishability and good mechanical properties. It is often used as a knife steel and impresses with its weldability, magnetizability, polishability and hardenability.
1.4057 X17CrNi16-2	€€€€€	€€€€	800 – 950 Hardened: 1520	310 Hardened: 445 HB (47 HRC)	Hardenable, martensitic steel with high strength and good corrosion resistance. It is well suited for welding, can be magnetized and hardened, which is why it is often used for heavily stressed machine parts.
1.4104 X14CrMoS17	€€	€€	650 – 850	220	Martensitic chromium steel with excellent machinability and good mechanical properties, which can be further improved by tempering. The stainless material can be magnetized and hardened.
1.4112 X90CrMoV18t	€€€€€	€€€€€	925 Hardened: 2180	265 (27 HRC) Hardened: 613 HB (59 HRC)	Corrosion-resistant, martensitic chromium steel that achieves exceptionally high hardness and wear resistance through heat treatment. It is also characterized by its excellent polishability, magnetizability and hardenability.
1.4301 X5CrNi18-10	€€	€€€	500 – 700	215	This is the stainless steel most frequently used for turning and milling work and impresses with a balanced ratio of all relevant material properties. It is non-magnetic, very good for welding, acid-resistant and resistant to low temperatures down to 0 °C.
1.4305 X8CrNiS18-9ei	€€€	€€	500 – 700	230	Thanks to its special composition, it is particularly well-suited for machining and is frequently used. However, compared to 1.4301, it has lower corrosion resistance and is not weldable. The material is non-magnetic and stands out for its excellent machinability.
1.4404 X2CrNiMo17-12-2	€€€€	€€€€	500 – 700	215	Characterized by exceptionally high corrosion resistance to acids and chloride-containing media. The non-magnetic material is highly weldable and is frequently used in the chemical industry.
1.4542 X5CrNiCuNb16-4	€€€	€€€€	930 Hardened: 1400	300 (32 HRC) Hardened: 388 HB (42 HRC)	Stainless, precipitation-hardenable chromium-nickel steel stabilized by niobium. This highly alloyed material combines high corrosion resistance with exceptional strength and ductility, making it particularly suitable for high-performance applications. It is highly weldable and hardenable.
1.4571 X6CrNiMoTi17-12-2	€€€€€	€€€€	500 – 700	215	Offers similar corrosion resistance and mechanical properties to 1.4404, but is characterized by better high-temperature strength. Machinability is somewhat more difficult, but the material is easy to weld, non-magnetic and acid-resistant.
1.4841 X15CrNiSi25-21	€€€€€	€€€€€	500 – 700	220	This silicon-alloyed, austenitic stainless steel is particularly suitable for use in high-temperature applications. It has good strength properties at temperatures up to 1150 °C and excellent corrosion resistance up to 650 °C. The material is easy to weld, non-magnetic and heat-resistant.
